Patented Dec. 9,1919.

To all/whom z'zf may concern Be -it 'known that I, ARTHUR E. EKoLA,

acitizen. of the UnitedV States, .residing vat' p Oskar, in the countyof Houghton, .State of C`l\[ichigan, have invented certain usefulImprovements in Vegetable-:Graters and I do hereby-declarethe followingto beafull, clear, Vand eXactdescrip/tion of the in vent-ion, such aswill enable others, skilledA in the art to which it appertains tovrmake;

and use the same.

Theinvention relates to-a grating ymachine, and more particularly to theclass of vegetable graters or'mashers. g The primary object lof theinvention is the provision of a machine of this charac-A ter, whereinvegetables or `the like when placed therein will 'be subjected toreversely Y movable grating lsurfaces so as to mash and reduce toa pulpsuch vegetables or the like with despatch.

Another object of the inventionl is'the provision of a machine -oftliischaracter, whereinl the operating removed from the body of the machineso as to enable the cleaning of the latter to render the same sanitaryand-such parts can be firmly fastened in place for thesuccessfulo'peration of the machine.

` A further object of the invention'is Athe provision of a machineofthis character,

wherein the construction thereof isvnovel in form to assuresimplicity,durability, etlicient in the operation and also one that is inexpensiveto manufacture.

With these and other objects-in view, theV invention consists in the-features'of conystruction,combination and arrangement of parts as willbe hereinafter fully described,

illustrated in the accompanying drawing and `pointed out in the claimshereunto appended.

The material such as vegetables, fruits or thelike, will be properly grated or mashed and delivered from thisstationary frame or machine. p Y

From the foregoing it is thought that the manner of construction and useof the device will be clearly understood, and therefore a more extendedexplanation has been omitted.

What is claimed is.: Y l. in a machine of the class described, thecombination with a hollow body having at its upper end a iiaring liange,and a fixed spider at t ie iowerend of the body having a central stepbearing, of an upper spider having angular ends fitting' within saidiiange, means for removably attaching them thereto, a shaft journaiedthrough the upper spider and resting in said step bearing, a tubularshaft surrounding said first shaft, cuter and inner grinding shellscarried respectively by said shafts, and a driving shaft mounted inbearings on the removable spider and connected with said other shaftsfor turning them simultaneously and oppositely. 2. ln a machine of theclass described, the combination with a hollow body having at its upperend a flaring iiange notched at one side and an internal shoulder at thebase Lof said flange, and a spider at the lower end shaft journaled insaid bearings and eXtending through the notch, operating means on itsouter end, and a driving gear on its inner end engaging said gears.

8. In a grater of the class described, the

combination with a body having .a flaring flange at its open upper end,and the grinding mechanism proper including an upright shaft; of aspider removably mounted in the upper end of the body and having angularends iitting within said flange and slotted, said shaft being journaledthrough this spider, staples within vthe flange passing through saidslots, hooks pivoted to the ends for engaging said staples,and drivingmechanism carried by and removable with the spider.A l

i. In a vegetable grater, the combination with a body open at both ends,spiders mounted within it, and driving mechanism carried by one spider;of concentric shafts journaled in the spiders, an outer grinder carriedby one shaft and having internal teeth, an inner grinder carried by theother shaft and having external teeth, the walls of said grindersconverging downward, connections between the driving mechanism andshafts for rotating the latter simultaneously and oppositely, and a wormon the exterior of the inner grinder for forcing the material downward.

In testimony whereof, I aiiix my signature, in the presence of twowitnesses.
